" FLYINGTMACHINE.

To all whom it may concern: 1

Be it known that I, HELLMUTH HIRTH, a;

at JohannisthaLBerlimin the" Empire of? Germany, have invented certain new and Flying-Machines of which the following is a specification. i I

This invention relates to a fiyingmachine arranged so thatithelifting power maybe ried and the speed of flight to the local circum'stances, for instance those 'present in landing and so-forth, in a manner hitherto impossible. y

A flying machine can generally only 'be tain given load, as the load to be carried by the'adjustment of thesupportingplane or surface relatively to thepropellar, on

deedpossible to temporarily carry even an overload "on; anlordinary fiyin machine, if the horizontal-rudder be snitaoly adjusted.

nently overcome a comparatively high presalso considerably reduce the safety of:oper- Now is. this invention an easy adaptation of the; ying machine to the roost arred conditions, evenduring flight itself, IiSTGJlderecl possible in'that the supporting sur-, faces or planes remain securely connected vided'with. the balancing planes; on the one shaft bearings, and preferably also the motor itselfl'on the other hanrham made Specification o1 Letters Eatent.

I parts remain approximately parallel 1n. ad uStinent. As' the balancing" planes always adjust themselves in the direction of tlightfthatie to say substan tially horizontally), it results as the action of the ad ustment that the supporting planes are inclined'mo're or less relatively to the direction of traveling (or'rat-her to the horizontaD and this is obtained without the supporting planeshaving to be displaceably arranged on the part carrying them (which preferably also'receives'theseat for the aviator and passenger and soforth). Now it is important that in spite of the displacement of the balancing lanes, the pro-1 peller shall not act in a (li orent direction than in the direction of travel prescribed by the said'planes, as only thuscan the best:

efiiciency be got frointhe propeller and motor. This is very important in long distance fl ghts with a heavy load and also for rising in the case of a restricted starting place; For this reason, according to this invention, not'only are thebalancing surfaces displaeed, b ut the propeller shaft also preferably together. with the motor is always so 4 displaced; that ,it'remains substantially par and with the balancing planes. .This In y be attained in asim'ple manner in theicase of a suitably jointed. flying machine'- by means of a suitable kinema'ticzconnection of the two partsito be displaced.

.The present, invention is more particu:

larly described with reference to the cons struction' shown in the accompanying drawingby way of example:

a indicates the actual body of the flying niachine. The supportingsurfaces or planes b with the necessary struts or stays and the traveling frame with wheels cand skids (l are secured to this body a, and the seatfor' the aviator and also that for the passenger is provided thereon. The motor j with its lso connected to it by means 'oia suitableigoint e in such a way that the motor together with its shaft h which ca'rpropeller; g, can'be raised or lowered on the goint 'e out ofthe'horizontal'. A sim ilar joint is iocated at} between the main.- Y

The details of construction of the machines may be altered. in Various The noi'el and characteristic jointing of the flying machine is the esseiifi'iil. fest-11m of the im'enti which gives 21. hit erto i i-attain ehle adaptability. nee, lesser load than the normal one is to he conveyed the machine may be adapted in s manner to do this, it the metoi and propellei' are lowered and the rear pain oi the frame raised. The balancing planes living Ways L11 1; adjust themselves snlstantislly horizontally and the propeller s 12ft remains, as is pret ershle, parallel with the balancing planes, While the nets-til body of the flying machine with the supporting planes is elevated at the front and thereby has at 1' lifting powei: it Slilillfll sdinstmen with 11 simi- 111 action allows the machine to rise in a, very short run With full utilization of thpow of the motel: Vice verse by employing this invention, the run out on lending may be greatly reduced, as by the previously mentioned. adjustment oi the flying machine, the supporting planes are placed ohliqiiiely and the ellieiency of the motor so far redosed that the flying machine descends slowly. The speed of flight 1 thereby eonsidei'ebly diminished, even While the motor 15 still working, while hitherto the speed was practically invariable,
